MORTISE ORV'HINGE GAG-E.

Specification of Letters Patent.

Patented June 26, 1906.

Application filed August 22, 1904- Renewed October 27, 1905. Serial No. 284,706-

To aZZ whom it may 0071106777 7 Be it. known that I, GEORGE D. MoLEoD, a

citizen of the United States, residing at Ohigages used for locating the countersink in a door or door-jamb for the registering wings of the hinge, for marking mortises in mortiseand-tenon work, and for similar purposes.

One object of my invention is to provide a simple, durable, and eflicient device of this character by means of which the length, breadth, and depth of the countersink or mortiselmay be marked by one application of the too Another object of my invention is to combine with a gage of this character an adjustable blade by means of which the tool may be used as a try-square or a bevel.

A further object of my invention is to im- 1 prove and simplify the construction and operation of tools of this character and thereby render them more durable and efficient in use and less expensive to manufacture.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and are rangement of parts, as will be more fully described, and particularly pointed out in the appended claims. 4

In the accompanying drawings, Figure 1 is a perspective view of my improved tool. Fig.

2 is a plan view of the opposite side of the same. Fig. 3 is a longitudinal sectional View. Fig. 4 is a similar view taken in a plane at right angles to the plane of Fig. 3. Fig. 5 is a transverse sectional View. Fig. 6

. is a detail sectional view showing the setscrew for adjusting the square and bevel blade.

Referring to the drawings bynumeral,1 denotes the body of the tool,which is preferably angular in form and provided upon oppositefaces adjacent to one of its sides with longitudinally-disposed ribs 2 and 3, so that the body is substantially T-shaped in cross-section.

In the face 4 of the body 1 is formed a longitudinally-disposed dovetailed groove 5, in

' the other, as clearly shown in Fig.

gage the beveled walls of said. groove. Tlns slide 6 carries upon its outer end a transversely-disposed head 7, which corresponds in shape toa cross-section of the body 1, so that when said slide is forced into the groove the head 7 forms a continuation of the body. The outer face of the slide 6 is providedwith a scale, as shown at.8, to indicate'the distance of the head 7 from the end of the body 1. The inner end of the slide 6 is tapered andbeveled, as shown at 9, in order that the said slide when removed from the groove 5 may be used as a screw-driver, the head 7 serviig as a handle, as will be readily understoo Extending transversely through the body. 1 adjacent to one of its ends is a bore 10 and I atransverse slot 11, which communicates with said bore and opens outwardly into the face 4 of the body. Slidably mounted in said bore, which is preferably circular in cross-section, is a cylindrical rod 12 carrying adjacent to one end a marking pin or point 13, which, extends through and slides in said the edges of said plate being beveled to enslot 11 and projects slightly above the face 4. Said rod is moved longitudinally in said groove to adjust its pin 13 toward and from the rib 2 upon the body, and it is adapted to be secured in its adjusted position by means of a set-screw 14, which is screwed into a threaded openingformed in the body 1 adj acent to the slot 11. and has formed upon it a tapered or conical portion 15, which is adapted to impinge against the rod 12 when the screw is driven into the said recess; The head of said set-screw lies in the countersunk portion of the body, so that it does not project above the face 4.

Formed in the body .1 and extending through its ribs 2 and 3 is a transverse bore 16, in which is slidably mounted a rod 17 carrying a marking-pin 18 adjacent to one of its ends.- Said rod 17, which is similar in construction to the rod 12, is adjustably secured in its bore by a set-screw 19, so that point 18 may be adjusted toward and from the face 4 of the body. I Said pin 18, it will be noticed, projects slightly beyond the rib 2 and is adjustable in a plane at right angles to a plane in which the pin-point 13 is adjustable. The pin-carrying rods 12 and 17 coact with the face 4 and rib 2 of the body and are preferably disposed opposite each 1 of the drawings.

Coacting with the opposite face 20 of the body 1 are two point-carrying rods 21 and 22, disposed in a plane parallel to the face 20,

and a third point-carrying rod 23 is disposedin a plane at right angles to said rods 21 and 22. Said rod 23 is slidably and adjustably mounted, by means of a set-screw 24, in a bore extending through the ribs 2 and 3 intermediate their ends, and the rods 21 and 22 are slidably and adjustably mounted, by means of set-screws 25 and 26, in bores extending transversely through the body 1 upon opposite sides of the center of the body. The point of the rod 23 is adjustable toward and from the face 20 of the body, and the point of therods 21 and 22 slide in slots 27, communieating with their bores, and are adjustable toward and from the rib 3.

In one end of the body 1 is formed a transverse groove or recess 28, inwhich is mounted an adjustable blade 29. Said blade is formed in one end with a notch 30, in one of its sides with a notch 31, and in the end adjacent to said notches with an angularly-disposed slot 32.

Extending through the ribs 2 and 3 of the body is a set-screw 33, which also passes through the slot 32 in the blade and the recess 28 in the body and has provided upon it a collar or enlarged portion which is adapted to bear against the blade to hold the same against movement.

Extending through the slot 29 adjacent to one of its ends is a pin 34, which is adapted to be engaged by the notch 30 in the end of the blade to hold the latter in a position at right angles to the body 1, as clearly shown in Fig. 4 of the drawings. When said notch 30 is disengaged from the pin 34, the blade 29 may be swung at any desired angle with respect to the body 1 to ermit the tool to be used as a bevel, the sai blade being secured in its angular positions by means of the set-screw 33.

In using my improved gage only the pointcarrying rods u on one of its faces are used during one app ication of the tool to the object to be marked. When it is desired to mark the location of the countersink for the registering wings of a hinge, the rod 23, the rod 21 or 22, and the slide 6 are preferably used, the rod 23 being adjusted so that its point will mark the depth of the countersink, the points ofthe rods 21 and 22 being adjusted to mark the breadth of said countersink, and the slide or extensible member 6 being adjusted to mark the length of the said countersink. When the parts are thus adjusted and the tool is placed against a door or door-jamb, said markingpoints upon the rods will mark the breadth and depth of the countersink, and by means of a knife or other pointed tool the length of the same, as indicated by the adjustment of the slide 6 and its head 7, may be marked. The operation of the point-carrying rods 12 and 17 is similar to that of the rods 23, 21, and 22 and will be readily understood from the foregoing explanation. Although the gage-rods may be used interchangeably for different kinds of work, it will be noticed that the rods 23, 21, and 22 are particularly adapted for mortiseand-tenon work and the rods 12 and 17 for hingework. Rods 21 and. 22 may be used in conjunction with rod 23 as a butt-gage where the butt is set farther in the j amb than in the door, so that it will not be necessary to have an extra gage or change one of the gage-rod It will be seen that the slide 6 and its head 7 may also be used as calipers, the scale 8 upon said slide indicating the distance between the head and the end of the body, and when said slide is removed from the body it may be used as a screw-driver, as will be readily understood.

By providing the blade 29 it will be seen that the tool is adapted for use as a trysquare or a bevel, according to the adjustment of the blade with respect to the body.

While I have shown and described the pre ferred embodiment of my invention, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantanges of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
